    • A comparison of low and high-order methods for the simulation of supersonic jet flows 
      Conférence invitée
      F. ABREU, Diego; T. V. DAURICIO, Eron; F. AZEVEDO, João Luiz; JUNQUEIRA-JUNIOR, Carlos (ABCM, 2021-11)
      The present work compares results for different numerical methods in search of alternatives to improve the quality of large-eddy simulations for the problem of a supersonic turbulent jet flows. Previous work has analyzed ...
    • Low-frequency resolvent analysis of the laminar oblique shock wave/boundary layer interaction 
      Article dans une revue avec comité de lecture
      BUGEAT, Benjamin; CHASSAING, Jean-Camille; SAGAUT, Pierre; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2022-04)
      Resolvent analysis is used to study the low-frequency behaviour of the laminar oblique shock wave/boundary layer interaction (SWBLI). It is shown that the computed optimal gain, which can be seen as a transfer function of ...
    • Continuing invariant solutions towards the turbulent flow 
      Article dans une revue avec comité de lecture
      PARENTE, Enza; FARANO, Mirko; DE PALMA, Pietro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe (The Royal Society Publishing, 2022-05)
      A new mathematical framework is proposed for characterizing the coherent motion of fluctuations around a mean turbulent channel flow. We search for statistically invariant coherent solutions of the unsteady Reynolds-averaged ...
    • Thermochemical non-equilibrium effects in turbulent hypersonic boundary layers 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINNELLA, Paola; GIUSEPPE, Pascazio; ccSCIACOVELLI, Luca (2022-04-28)
      A hypersonic, spatially evolving turbulent boundary layer at Mach 12.48 with a cooled wall is analysed by means of direct numerical simulations. At the selected conditions, massive kinetic-to-internal energy conversion ...
    • Assessment of a high-order shock-capturing central-difference scheme for hypersonic turbulent flow simulations 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINELLA, Paola; GIUSEPPE, Pascazio; ccSCIACOVELLI, Luca (Elsevier, 2021-11)
      High-speed turbulent flows are encountered in most space-related applications (including exploration, tourism and defense fields) and represent a subject of growing interest in the last decades. A major challenge in ...
    • Finite-rate chemistry effects in turbulent hypersonic boundary layers: A direct numerical simulation study 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINELLA, Paola; GIUSEPPE, Pascazio; ccSCIACOVELLI, Luca (American Physical Society, 2021-05)
      The influence of high-enthalpy effects on hypersonic turbulent boundary layers is investigated by means of direct numerical simulations (DNS). A quasiadiabatic flat-plate air flow at free-stream Mach number equal to 10 is ...
    • Numerical Investigation of High‑Speed Turbulent Boundary Layers of Dense Gases 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINNELLA, Paola; GRASSO, Francesco; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Springer, 2020-03)
      High-speed turbulent boundary layers of a dense gas (PP11) and a perfect gas (air) over flat plates are investigated by means of direct numerical simulations and large eddy simulations. The thermodynamic conditions of the ...
